Congenital central hypoventilation syndrome (CCHS): management
Written and reviewed by Dr Ibrahim Imam, Consultant Neurologist. Last reviewed .
Congenital central hypoventilation syndrome (CCHS): management. This is caused by mutations in the PHOX2b gene on chromosome 4p.
Genetics
- This is caused by mutations in the PHOX2b gene on chromosome 4p
- This is usually a polyalanine repeat expansion mutation
- Non polyalanine repeat mutations (NPARM) have a worse phenotype
- The transmission is autosomal dominant
